Part of situation: Development of Scaffolded DNA computer (3 clusters)

Maynooth University researchers develop first-of-its-kind DNA computer

DNA computer molecular computing bioinformatics Maynooth University Scaffolded DNA Computer

Researchers at Maynooth University have developed a first-of-its-kind DNA computer, described as one of the most complex and fastest molecular computers reported to date. The study, published in the journal Nature, introduces the Scaffolded DNA Computer (SDC) system.

Unlike traditional silicon-based computers, this system uses a long DNA strand as a scaffold with shorter DNA strands that interact to perform computations. The process requires no continuous electricity; instead, it utilizes molecular interactions in a water and salt solution, triggered by a cycle of heating and cooling. The system reaches an equilibrium where the stable molecular structure represents the correct answer.

The team successfully ran ten different programs, including 100-bit computations. In one instance, the computer performed addition on numbers ranging from 11 million to 34 million. The researchers noted that while it is not as fast as silicon, it is the fastest DNA computer developed so far. The device proved to be robust and reusable, capable of performing up to 25 consecutive calculations. This breakthrough offers potential applications in energy-efficient computation, long-term data storage, and molecular systems for disease detection inside cells.
